GM and everyone else have to meet 35mpg across the board.
The 3.6SIDI probably cost as much to make as the LS3, especially when you bring in the cost of the super high output fuel pump and fuel system that has to handle the now thousands of PSI that is being pumped, but the engines are producing equal power to V8 couterparts of several years ago. But yes the fuel economy and the lower emissions via the direct injection help out the whole cause.
Everyone will start rolling out new and better systems on how to make more power out of much smaller packages. 300hp turbo 4cyl are only a step away.

Al:
EPA numbers are not of my concern in this case. Realized MPG is what I care about. Do you have info on that? Would be cool to see. Same with torque numbers.
